AGC: Shorthand for "A Good Cartoon." Basically, you intentionally interpret a comic with a fairly obvious bad message as having a good message. The original point of this was to poke fun at some of the really poor metaphors that some cartoonists were crafting, but the concept of AGC has been run into the ground. If you want to see some quality ones, Saint Sputnik has a blog dedicated to these.

Benghazi: While I think everyone is familiar with the Benghazi attacks, newer users might be unaware that one of the victims was Sean "vilerat" Smith, who was a long-time member and moderator of D&D. Seeing cartoonists use the death of a sincerely missed member of the community as a desperate attempt to smear Obama has made Benghazi a rather sore issue for everyone in this thread.

Can't Handle: The thread is known for getting into spats over ridiculous subjects. However, this phrase was used waaaaay too much, and you're not being witty by yelling "Can't Handle!" when people arguing over actual political stuff as opposed to goofy shit like weathervanes. Yes, we have actually argued over weathervanes.

DASGC: Stands for "Dumb and so Goddamn Crazy." A cartoon that portrays the opposing side as spastic, ignorant children, and their own side as patient, knowledgeable adults. Based on a Shmorky cartoon.

Don't Be Willfully Dense: A line from cartoonist Eric Allie when someone pointed out how stupid his cartoon was. Has become a thread motto of sorts to not be an idiot when interpreting the message of any given cartoon.
